GalleryHosted is an image hosting site, it lets you upload and host photos for free, and gives you hotlinks for you to link your website. Most parts are similar other image hosting sites, but the interesting point that I liked is, it lets you create each gallery for your photos, you can upload multiple photos together, and makes thumbnail size for your website that displays whole photos that from gallery. The best point is it also lets people one click to download whole photo gallery.
